Evolution Vocab

1. all of the genes/alleles present in a population
3. a species evolving in response to the evolution of another species
6. a form of evolution where two species not closely related to one another develop similar structures
8. a structure that is present as a result of existing in an ancestor, but now serves no purpose to the living species
9. a developed trait that increases the fitness of an organism
11. the process of genes in a population moving in a particular direction not associated with natural selection
12. the prevalence of a particular gene in a population
13. a form of evolution where a species become the ancestor to two distinct species over time
14. the process of a species or population changing so much over a long period of time that it becomes an entirely new distinct species
16. - the separation of a population that impacts their ability to reproduce with other members of the population in some way
17. the separation of a species into distinct population by a natural barrier

1. the movement of genes from one population of a species to another
2. a similar structure that form in closely-related organisms that have changed due to a difference in function
4. A similar structure that appears in species that are not closely related to one another
5. the ability of an organism to survive and reproduce in nature
7. the process of certain traits being more advantageous in nature, leading to the most fit individuals of a population or ecosystem to survive, reproduce, and pass on their genes
10. reduced genetic diversity of a population as a result of very few original members of a population
15. the study of how species are distributed geographically. This tells us how species migrated over time and how this impacted their evolution.
